BLIND-OPERATING DEVICE;

SPECIFICATION forming part of Letters Patent No. 732,262, dated June 30, 1903.

Application filed November 12, 1902. Serial No. 131,020. (No model.)

To all whom it may concern.-

Be it known that I, NATHAN O. BOND, a citizen of the United States, residing at Hyannis, in the county of Barnstable and State of Massachusetts, have invented certain new and useful Improvements in Devices for Operating Blinds; and I declare the following to be a full, clear, and exact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention relates to devices for operating blinds from the inside of the house; and it consists in a novel construction and arrangement of parts by means of which extreme simplicity of construction and direct application of power in opening and closing the blinds and securely locking them in either position are obtained.

In the drawings, Figure 1 is an elevation from the outside of a blind, showing the outer portion of the device. Fig. 2 is a similar View from the inside of the window-casing, showing the operating-handle and locking mechanism. Fig. 3 is a vertical cross-section on the line 3 3 of Fig. 1, showing the application. of the device to the casing and relative arrangement of parts. Fig. 4 is a sectional plan View with the blind partially open to illustrate the movements of the parts. Fig. 5 is a detail of the operating and locking handle, illustrating its movement in locking and releasing; and Fig. 6 is a detail of the outside casting, which the operating-pin engages to move the blind.

In the drawings, 1 is ablind hinged to swing in the usual manner in a window-casing 2.

A is an operating-rod passed through an opening bored in the casing at an angle of approximately forty-five degrees, within which it rotates in suitable bearings a a, which will be further described. 1

The outer end of the operating-rod is bent at right angles and forms, in effect, a lever or pin B, adapted to engage within a slot 0,

formed in a casting D, carried on the outer surface of the blind. I

The casting C may be formed in one piece, but is preferably formed of a curved baseplate 0, provided with lugs c 0, having screwholes 0 0 by whichit may be attached to the blind, and with a raised rib 0', upon which the pin B operates during the closing movement of the blind, and a confining guard or wire C secured in the base-plate 0, preferably during the casting of the same, upon which the pin B operates to open the blind. The base-plate c and rib c, as well as the guard 0 are curved, as shown in Figs. 3 and 4, to clear the end of the pin B from the surface of the blind as the pin is rotated to operate the blind.

The inside end of the operating-rod A is flattened, as shown at M, and is provided with a handle D,pivoted thereto and provided at its upper end with cam-surfaces (Z don each side of the pivot (L adapted to act upon the surface of the bearing a in such manner as to lock the moving parts, as Will be further described.

The bearings a a consist of cylindrical castings provided with suitable openings,in which the rod A revolves, and with lugs e e, by which they are secured to the Window casing and are mounted in suitable holes bored in the easing. The outer bearing is preferably formed with a cup-shaped depression in its outer surface to prevent the accumulation of snow and sleet and consequent interference with the operation of the parts.

The action of the device is very simple. The handle is raised from its normal locked position to the position shown in dotted lines in Fig. 5 and rotated in an arc of aboutone hundred and eighty degrees and is then depressed to the position shown in full lines in said figure, which depression causes the camsurfaces to act upon the face of the inner bear- .in position. A reversal of this motion will close the blind and lock the parts in a similar manner.

What I claim, and desire to secure by Letbind against the outer surface of the lower ters Patent, is bearing substantially as shown. IO
